, LUBRIGATING DEVICE.

To all whom it may concern:

Be it'known that I, AUGUST F. KIRSCH- BAUM, a citizen of the UnitedStates, residinguat St. Paul, in the county of- Ramsey and State ofMinnesota, have invented cer-' tain new and useful Improvements in Lu 1bricating Devices, of which the following is larly to provide animproved device for.voil-' ing the guideways for elevators and forequivalent uses, and to this end consists in the features ofconstruction, combination,

a specification.

My invention relates to improvements-in lubricating devices, its objectbeing-particuand arrangement of parts hereinafter described and claimed.

In the accompanying drawings forming part of this specification, Figure1 is a top view of my improved device shown in connectionwith anelevatorguideway; Fig. 2 is a side elevation of the same partly brokenaway; Fig. 3 is a front elevation shown sectioned on line w-m of Fig. 1;and Fig. A is a detail view of an actuating lever forming part of theinvention.

Referring to the drawings A represents a receptacle for the oil providedwith a suit able cover 2, the receptacle being supported upon theelevator B as by means of brackets 3. The elevator forming no part of myinvention is only shown fragmentarily. Leading from the bottom of thereceptacle is a downwardly extending conduit plug 4 tapped into which isa laterally and downwardly extending tube 5. constituting a dischargeconduit for the oil. Slidable in the tube 5 is a plunger 6, normallyheld outward by acoil spring 7 arranged within the tube and interposedbetween the plunger and conduit closing plug 8.. The plunger 6 is loosewithin the pipe 5 to allow oil to pass over it, the free end of theplunger wiping the guideway 9 to deposit the 011 thereon. conduit isclosed by a valve formed by the lower end of the rod 10, said rod at itsupper end having ivotal connection 11 with the outer end 0 a link 12.supported on a transverse rod 13 journaled in the sides of thereceptacle. The rod 13 is normally held in position closing the valve bymeans of a spring 14: connecting one end of the rod with the receptacle.Secured upon the opposite end of the rod is an arm 15, said arm at itsfree end pivotally supporting an extensionarm 16 through the medium of aSpecification of Letters Patent.

pivot 17. The extension arm 16 is normally I held in alinement with thesupporting arm 15 by means of a lateral finger 18 carried by the innerend of the extension arm, the finger 18 being normally held in contactwith the underside of the arm 15 by the overweighted outer end of theextension arm. The outer end of the extension arm is thus free to swingupwardly but is held against swinging downwardly. A stop 19 ispositioned at a suitable point along the guideway to engage with theextension arm, as indicated in Fig. 1. v In use, the elevator as ittravels upwardly upon the guideway, carrying with it the lubricantreservoir, will cause the free end of the extension arm 16 to beobroughtinto contact with the stop 19. As the elevator continues to travelupward the engagement of the stop 19 with the. arm 16 will, through theintermediate mechanism, lift the valve 10 and allow a certain quantityof oil to pass downwardly through the discharge tube around the plunger6, the oil being wiped upon the guideway by the plunger. As theextension. arm 16 is carried past the stop 19 the parts will berestoredto normal position by the spring 1 1. In the downward travel of theelevator, the engagement of the stop 19 with the extension arm 16 turnssaid arm upon its pivot without affecting the normal position of theparts. Any desired number of the stops 19 may be used to regulate theamount of oil discharge from the reservoir. 7 I 7 While I have shown myinvention applied to an elevator for oiling the guideway, I.
